Abstract
The invention discloses a kind of preparation methods of the poly- fragrant oxadiazoles fiber of original liquid coloring, its main feature is that carrying out in accordance with the following steps: dyestuff is added in 98% concentrated sulfuric acid, is slowly dissolved in concentrated sulfuric acid, chromogen liquid by the preparation of poly- virtue oxadiazoles stoste；Poly- fragrant oxadiazoles stoste after aromatic diacid is polymerize with hydrazonium salt is cooled to 90-100 DEG C in polymeric kettle；After poly- fragrant oxadiazoles stoste drops to 90-100 DEG C, chromogen liquid is slowly added into poly- fragrant oxadiazoles stoste, it is stirring while adding, while controlling poly- fragrant oxadiazoles stoste temperature and must not exceed 100 DEG C；It is to be mixed uniformly after, carry out deaeration into deaerator, carry out wet spinning after the completion of deaeration, coloured fiber is made, fiber color is uniform and bright-coloured.It is an advantage of the invention that original liquid coloring method is by adding colorant in fiber stoste, coloring and spinning can be carried out continuously simultaneously, uniform coloring, good color fastness, and dye-uptake is high, with short production cycle.At low cost, pollution is also few.
Description
Technical field
The invention belongs to the poly- fragrant oxadiazoles fiber of macromolecular fibre technical field more particularly to a kind of original liquid coloring and its systems
Preparation Method.
Background technique
Poly- virtue oxadiazoles fiber true qualities are faint yellow or yellow, and color is more single, but due to it in occupational protection and
The application of apparel industry proposes the more abundant requirement of color to the color of fiber.The dyestuff for the POD dyeing reported at present
Including acid dyes, the dye of positive ion, disperse dyes and reactive dye, but net assessment gets off, reactive dye K/S value compared with
Low, acid dyes and dye of positive ion crock fastness are poor, and the sample light fastness of disperse dyeing is relatively low, only
Disperse dyeing effect is more excellent, and disperse dyeing process temperature is high, of long duration, but unfriendly to environment.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a kind of poly- fragrant oxadiazoles fiber of original liquid coloring and
Preparation method, coloring and spinning are carried out continuously simultaneously, and uniform coloring, good color fastness, dye-uptake is high, with short production cycle, cost
Low, pollution is also few.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of preparation method of the poly- fragrant oxadiazoles fiber of original liquid coloring, its main feature is that carrying out in accordance with the following steps:
The preparation of the poly- fragrant oxadiazoles stoste of step 1；
The preparation of step 2 chromogen liquid: dyestuff is added in 98% concentrated sulfuric acid, is slowly dissolved in concentrated sulfuric acid, forms m%'s
Chromogen liquid；
Poly- fragrant oxadiazoles stoste after aromatic diacid polymerize by step 3 with hydrazonium salt is cooled to 90-100 in polymeric kettle
℃；
It is former that step 4 is slowly added into poly- fragrant oxadiazoles after poly- fragrant oxadiazoles stoste drops to 90-100 DEG C, by chromogen liquid
It is stirring while adding in liquid, while controlling poly- fragrant oxadiazoles stoste temperature and must not exceed 100 DEG C；
Step 5 it is to be mixed uniformly after, carry out deaeration into deaerator, carry out wet spinning after the completion of deaeration, coloring is made
Fiber.
Further, gather in the step 3 and step 4 after fragrant oxadiazoles stoste drops to 90 DEG C, chromogen liquid is slowly added
Enter into poly- fragrant oxadiazoles stoste.
Original liquid coloring is that colorant appropriate is added in spinning solution, can also by adequately mixing, dissolving and filtering
Quantitative injection toner or coloured stoste before entering spinning head, are spun into colored fibre after static mixer mixes.It is viscous
The original liquid coloring of the fibers such as glue/acrylic fibers belongs to such.This technique of original liquid coloring belongs to physical change, and advantage is coloring and spins
Silk can be carried out continuously simultaneously, uniform coloring, good color fastness, and dye-uptake is high, with short production cycle, at low cost, and pollution is few.
Containing polar group as oxadiazoles ring and hydrazides group in POD molecule, it is good to guarantee that fiber and dyestuff have
Affinity interaction power so that dyeing is carried out, as observation using wet spinning made from the fibre section POD and surface
The scanning electron microscope (SEM) photograph of form does not have the defects of hole it can be seen that fibre structure is finer and close, but cross sectional shape is irregular, has
Skin-core structure, fiber surface have obvious longitudinal groove structure, and rough surface is conducive to dyestuff and enters fibrous inside, in addition, passing through
XRD detection shows that the crystallinity of fiber is not high, and the stainability of fiber is also relatively good.
A kind of poly- fragrant oxadiazoles fiber of original liquid coloring, its main feature is that the poly- fragrant oxadiazoles fiber of the original liquid coloring is by above-mentioned system
Preparation Method is prepared.
Compared with prior art, it is an advantage of the invention that original liquid coloring method be by adding colorant in fiber stoste,
Coloring and spinning can be carried out continuously simultaneously, uniform coloring, good color fastness, and dye-uptake is high, with short production cycle.It is at low cost, pollution
It is few.
Specific embodiment
The present invention will be further described combined with specific embodiments below.
A kind of preparation method of the poly- fragrant oxadiazoles fiber of original liquid coloring, its main feature is that carrying out in accordance with the following steps:
The preparation of the poly- fragrant oxadiazoles stoste of step 1；
The preparation of step 2 chromogen liquid: dyestuff being added in 98% concentrated sulfuric acid, be slowly dissolved in concentrated sulfuric acid, forms chromogen
Liquid；
Poly- fragrant oxadiazoles stoste after aromatic diacid polymerize by step 3 with hydrazonium salt is cooled to 90 DEG C in polymeric kettle；
Chromogen liquid is slowly added into poly- fragrant oxadiazoles stoste by step 4 after poly- fragrant oxadiazoles stoste drops to 90 DEG C,
It is stirring while adding, while controlling poly- fragrant oxadiazoles stoste temperature and must not exceed 100 DEG C；
Step 5 it is to be mixed uniformly after, carry out deaeration into deaerator, carry out wet spinning after the completion of deaeration, coloring is made
